Crystal growth, spectroscopic, optical, thermal and hirshfeld surface analysis of glycinium hydrogen fumarate glycine solvate monohydrate (GHFGSM): A third harmonic nonlinear optical organic crystal

摘要

An efficient nonlinear optical single crystal, GHFGSM was grown by solvent evaporation method. Single crystal XRD evince that GHFGSM crystallized in monoclinic system with centric space group P21/n. The composition of different functional groups in GHFGSM was identified with FTIR spectral investigation. The UVevisible and fluorescence spectrum proved the optical and electronic properties respectively for the grown crystal. The various optical parameters such as extinction coefficient, reflectance, and linear refractive index, electrical and optical conductivity were also determined. Inter molecular interaction in the compound was studied using Hirshfeld Surface generated by crystal explorer 3.1 program. The thermal firmness of the grown crystal was decided by thermogravimetric analysis and accurate melting point was confirmed from differential scanning calorimetry. The dielectric property of the grown crystal was examined for different temperatures. The third harmonic generation in GHFGSM has been investigated using Z-scan technique employing Nd:YAG laser and thus this technique clearly suggest its suitability in emerging technologies such as optoelectronics and third order nonlinear optical applications.
